Dynamic process state adjustment of a processing tool to reduce non-uniformity |
摘要 |
A method and an apparatus for reducing process non-uniformity across a processed semiconductor wafers. A first semiconductor wafer is processed. A process non-uniformity associated with the first processed semiconductor wafer is identified. A feedback correction in response to the process non-uniformity during processing of a second semiconductor wafer is performed and/or a feed-forward compensation is performed in response to the process non-uniformity during a subsequent process performed across the first semiconductor wafer is performed.
